Applying armature removes weighted vertex/armature?
Actually, I think i found an answer. I marked my character and applied it's location, scale, and rotation to "3D cursor" at center, and then made the armature. And it works now. But thanks anyway, I did learn something or two :) It must have been something about the mirroring on negative scale ? All my normals had to be flipped once I did that. Have a nice day!
